Why I think Lightmass is completely out of Date

This looks good but we have to wait and see if it really is better or if it just has other problems. Also we need to see how the renderer works once you put 300.000 vert vray assets in the scene ;). Does it support real time at all? It’s good to have an instant preview but do be honest I think I would go mental if I had to work with this feature.

I don’t agree that light mass is very slow. It is only slow if you change certain settings. A preview build takes a lot less time and it will give you a good impression of what the production render will be.
